Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022784, here are decompositions:

11 + 1022773 = 1022784
23 + 1022761 = 1022784
83 + 1022701 = 1022784
101 + 1022683 = 1022784
107 + 1022677 = 1022784
131 + 1022653 = 1022784
151 + 1022633 = 1022784
173 + 1022611 = 1022784

Showing the first eight; more decompositions exist.
